The current gain of a transistor in CE configuration is defined as the ratio of output current or collector current (IC) to the input current or base current (IB).

In CC configuration, the collector terminal is grounded so the CC configuration is also known as grounded collector configuration.

The current gain of a CC amplifier is high.

Dynamic input resistance is defined as the ratio of change in input voltage or base voltage (VBC) to the corresponding change in input current or base current (IB), with the output voltage or emitter voltage (VEC) kept at constant.

The input resistance of common collector amplifier is high.

In pulse triggering, the gate is supplied with single pulse or a train of pulses. Here the gate drive discontinuous or doesnot need pulse to turn the scr and hence gate losses are reduced in greater amount by applying single or periodically appearing pulses.

DRAM is a type of volatile memory used in computers and other digital devices to temporarily store data that the CPU is actively using.
The memory size of DRAM chips can vary depending on the specific application and computing requirements.
In modern computers, DRAM capacities have significantly increased, and it is common to find DRAM modules with sizes ranging from a few gigabytes (GB) to several tens of gigabytes. However, historically, DRAM modules in the range of 16 to 256 MB were commonly used in older computer systems.

DRAM consumes less power compared to SRAM. It has more area as well. Thus both cache and DRAM together are used for main memory.

Always, for EEPROM, the initial value will be 1.

The process of giving input is called encoding. here, we give music as input. Thus the answer is (a).

The emitter terminal and common base terminal are known as input terminals whereas the collector terminal and common base terminal are known as output terminals.
